librecad

Librecad is an application for computer aided design (cad) in two dimensions (2d). with librecad you can create technical drawings such as plans for buildings, interiors, mechanical parts or schematics and diagrams.

This version has the same good drawing features as before, some of them improved. Exporting high quality images for publications is still problematic - svg output was added, which is a good thing, but some basic output features (jpg, png, svg), in particular if in color, can crash your whole sesson (requering new login and crashing all your other programs). Be very careful with this.
